[ckan-dev] Running DataPusher on Apache

Fri Oct 18 00:48:45 UTC 2013

Hi,

With David's help, I was able to solve the issue. The first problem was
with my Apache configuration file. I changed it to be more similar to
https://github.com/kindly/ckan-azure/blob/master/datapusher.

SELinux also was to blame. I adjusted the SELinux configs as in
https://github.com/okfn/ckan/wiki/How-to-Install-CKAN-2.0-on-CentOS-6.3#adjust-the-selinux-file-contexts
.

I guess that was it.

Cheers!
